Federated Learning: Breaking Down Barriers in Global Genomic Research.

Area of Science:

• Genomics and Bioinformatics
• Computational Biology
• Data Science

Background:

• Next-Generation Sequencing (NGS) has advanced genomic research, enabling personalized medicine and population genetics.
• Data silos, privacy concerns, and regulatory hurdles impede large-scale genomic data integration and collaboration.
• Federated Learning (FL) offers a decentralized approach to data analysis, preserving privacy and adhering to regulations like GDPR.

Purpose of the Study:

• To explore the application and potential of Federated Learning (FL) in the field of genomics.
• To detail the methodology of FL for genomic data analysis, including privacy-preserving techniques.
• To examine the challenges and regulatory considerations, such as GDPR, for implementing FL in genomics.

Main Methods:

• Review of Federated Learning methodologies: local model training, secure aggregation, and iterative refinement.
• Analysis of FL's suitability for decentralized genomic data analysis.
• Examination of challenges: heterogeneous data integration and cybersecurity risks.

Main Results:

• FL enables decentralized analysis of genomic data, addressing privacy and regulatory concerns (e.g., GDPR).
• Successful implementations in global and national initiatives demonstrate FL's scalability and collaborative potential.
• FL facilitates secure data sharing and model building across multiple institutions without centralizing sensitive data.

Conclusions:
